The Detroit Tigers hired Scott Harris as president of baseball operations Monday, choosing the San Francisco Giants' general manager to run the organization as it tries to transition from a half-decade-long rebuild to contention.

Harris, long seen as a rising star in front-office circles, spent the last three seasons with the Giants, working alongside president of baseball operations Farhan Zaidi to build the team that won 107 games in 2021. Previously, Harris had spent seven seasons with the Chicago Cubs, ascending to assistant general manager and playing an integral role in their World Series-winning 2016 season.

The Detroit Tigers have signed Daniel Ponce de Leon to a Minor League deal this week.

The right-hander made his debut for the organization on Tuesday with Triple-A Toledo.

Ponce de Leon hasn't appeared in a Major League game this season, but he's spent time with the Seattle Mariners and Washington Nationals organizations.

The 30-year-old pitched 33 1/3 innings for the St. Louis Cardinals in 2021, posting a 6.21 ERA and 24 strikeouts.

The San Francisco Giants have agreed to a contract extension with Wilmer Flores that guarantees the infielder $16.5 million over the next three seasons and could be worth up to $21.5 million.

Flores gets salaries of $6.5 million each in 2023 and 2024. The contract also  includes an $8.5 million club option for 2025. If the team declines, Flores has a $3.5 million player option.

The 31-year-old is hitting .233/.317/.410 with a career-high 18 home runs in 463 at-bats this season.
